Notes on Operation

• When the reset signal is input, the valve spool is returned to the neutral position by the built-in reset mechanism. Always supply the pilot pressure for sizes 03 and above. When the pump is to be started up, input the reset signal to the controller or driver to set the valve to the reset status, and then start up the pump, and when the pump is running normally, release the reset signal.

• A neutral position adjustment mechanism is provided on the outside of the valve, but its re-adjustment is not necessary since the adjustment was completed prior to shipment from the factory.

• Connect the drain pipe directly to the tank. The allowable back pressure is 0.35 MPa.

Mounting Bolts (JIS B 1176 Strength Grade 12.9 or Equivalent)

• The mounting bolts are not provided with the valve bodies and must be ordered separately.

• Mounting bolt tightening torqueD-DFG-01: 7～8 N·mD-DF (R) G-03: 12～15 N·mD-DF (R) G-04: M6 (1/4-20UNC) 9～14 N·m M10 (3/8-16UNC) 50～60 N·mD-DFG-06: 75～81 N·mD-DFG-06: 230～290 N·m
